Nike used VMware Integrated OpenStack in conjunction with NSX to deploy applications in minutes.
Well, I got to tick a big item off my list of goals last week. I successfully delivered a presentation at Cisco Live! in front of a large group of people. It didn't kill me and I didn't trip over anything and embarrass myself so no matter what, I have those two points to feel good about :-)
Me starting my presentation
All joking aside, it actually went a whole lot better than that.
Eighty-three organizations and individuals from Australia, Canada, New Zealand, the United Kingdom, and the United States are insisting governments support strong encryption.
The letter, which was sent to government representatives in each of the above countries, called for public participation in any future discussions. It comes on the heels of the “Five Eyes” ministerial meeting in Ottawa, Canada earlier this week.
The Internet Society supports the substance of the letter.
I'm not only one weary of Cisco's buggy products and half-baked strategies.

What is urban and rural area ? What is underserved area in networking ? These definitions are heavily used in networking. And all broadband network designers take always these definitions into an account while they do their design. I think knowing these definitions as a network engineer is valuable for you. In general, […]

In a recent blog post, my colleague Marek talked about some SSDP-based DDoS activity we'd been seeing recently. In that blog post he used a tool called mmhistogram
to output an ASCII histogram.
That tool is part of a small suite of command-line tools that can be handy when messing with data. Since a reader asked for them to be open sourced... here they are.
Suppose you have the following CSV of the ages of major Star Wars characters at the time of Episode IV:
Anakin Skywalker (Darth Vader),42
Boba Fett,32
C-3PO,32
Chewbacca,200
Count Dooku,102
Darth Maul,54
Han Solo,29
Jabba the Hutt,600
Jango Fett,66
Jar Jar Binks,52
Lando Calrissian,31
Leia Organa (Princess Leia),19
Luke Skywalker,19
Mace Windu,72
Obi-Wan Kenobi,57
Palpatine,82
Qui-Gon Jinn,92
R2-D2,32
Shmi Skywalker,72
Wedge Antilles,21
Yoda,896
You can get an ASCII histogram of the ages as follows using the mmhistogram
tool.
$ cut -d, -f2 epiv | mmhistogram -t "Age"
Age min:19.00 avg:123.90 med=54.00 max:896.00 dev:211.28 count:21

Another question from someone watching my Designing Active-Active and Disaster Recovery Data Centers webinar (you know, the one where I tell people how to avoid the world-spanning-layer-2 madness):
In the video about parallel application stacks (swimlanes) you mentioned that one of the options for using the R/W database in Datacenter A if the user traffic landed in Datacenter B in which the replica of the database is read-only was to redirect the user browser with the purpose that the follow up HTTP POST land in Datacenter A.
Here’s the diagram he’s referring to:
Read more ...Some may find the title a bit strange, but, actually, it’s not 100% wrong. It just depends on what the acronym “DCI” stands for. And, actually, a new definition for DCI may come shortly, disrupting the way we used to interconnect multiple Data Centres together.
For many years, the DCI acronym has conventionally stood for Data Centre Interconnect.
Soon, the “Data Centre Interconnect” naming convention may essentially be used to describe solutions for interconnecting traditional-based DC network solutions, which have been used for many years. I am not denigrating any traditional DCI solutions per se, but the Data Centre networking is evolving very quickly from the traditional hierarchical network architecture to the emerging VXLAN-based fabric model gaining momentum in enterprise adopting it to optimize modern applications, computing resources, save costs and gain operational benefits. Consequently, these independent DCI technologies will continue to be deployed primarily for extending Layer 2 and Layer 3 networks between traditional DC networks. However, for the interconnection of modern VXLAN EVPN standalone (1) Fabrics, a new innovative solution called “VXLAN EVPN Multi-site” – which integrates in a single device the extension of the Layer 2 and Layer 3 services across multiple sites – has been created for a Continue reading
